SPECIFICATION forming part of Letters Patent No. 341,029, dated May 4, 1886.

Application filed August 18, 1885. Serial No. 174,701. (Model.)

had therein to the accompanying drawings.

My invention has relation to steam injectors and ejectors, as more fully hereinafter described and set forth.

In the accompanying drawings7 Figure lis a longitudinal sectional View of my injector.

Fig. 2 is an elevation of the combiningtube. Fig. 3 is an elevation of one end of my invention.

The object of my invention is to form an adjustable lifting injector and ejector withasingle row of tubes, and not regulated by any changes of the steam-supply, but by different positions of the mixer and discharge tubes. I accomplish this result by combining the mixer and discharge tubes, and prolonging the dischargetube suiiiciently to project beyond the shell l. To the rear end of this combining-tube 2,1 attach aliandle, 3, said handle having arms 4 extending forward ,having on their ends beveled lips 5, made so as to work in the grooves of the' large threaded neck 6 on the rear end of the injector, to enable the operator to adjust the said tube 2 to any position required by the working of the machine, and to enable him to tell by the position of the said handle j usthow the machine is feeding.

llhe combining-tube 2 is provided with suitable perforations, 7 8 9, for the overflow and discharge. I also provide for a stuffing-box, l0, which screws on the threaded neck ll at the end of the large threaded part 6,said stuffingbox having a iiange,which extends nearly to the arms ,and prevents the combining-tube 2 from slipping completely out without first unscrewing the stufling-box l0. Into the front end of said tube 2 is secured a mixer-tube or nipple, 12,which has a perforation, 13, corresponding to the perforation 7 in the combined tube.

Inside of the steam-pipe connection 14 is secured the force-tube 15, Which extends far enough into the water-pipe 16 to allow the combining-tube 2 to iit closely over its small end and form an injector. The shell or body of the injector has in its upper face three perforations, 16 17 p 18, said perforations being stopped by screw-plugs, thus rendering access to the inside of the injector easy, and facilitating the cleaning of the same, the threads in said openings being pipe-size threads, to allow of pipes being connected to that side, if necessary. The central perforation, 18, is for the purpose of an overfiow-valve having a loose disk, 19, covering the bottom opening, and having an upright piece, 20, attached to its upper face, said piece working in an opening, 2l, in the bottom of the plug, and preventing the disk from ascending too far or turning over.

In order to draw or lift Water I pull the combining-tube 2 backward by turning the handle 3, causing the lips 5 on the arms 4 to follow the grooves of the large threaded neck 6, thus enabling the steam issuing from the steam-tube l5 to pass off through the overflow Without having to go through the mixer-tube. When the water appears at the overflow I screw the combining-tube 2 forward toward the steam-tube 5 until the water stops coming out of the overflow. Thus I can at will form an ejector or an injector, and regulate the supply of water according to the given pressure or the amount of steam required. It will be seenV that the perforations 7 enable the water and steam to pass off through these perforations (one being on either side of the tube 2 and opposite each other) while you push the tube forward, and the perforations 8 are within the solid shell l, between the perforations -17 and 18. These perforations 7 also render the injector automatic, because, under a small pressure only, they start themselves when interrupted (breaking) as the steam blows out of these holes until the water in 16 gets suiiicient body to condense the steam-jet again.

If the injector gets hot from any cause, Ican take out the combining-tube 2, give steam, and draw Water any reasonable height. The water thus lifted and thrown out rapidly cools the shell or body l.

To facilitate the inspecting and cleaning of the machine I arrange for perforations in the casing opposite the pipe-connections for the passage of the steam and water while the combining-tube is pushed forward.

Having described my invention, what I claim IOO as new, and desire to Secure by Letters Patent, 1s-

1. In an ejector and injector, as above described, the shell or body l, having perforations 16 17 18, having screw-plugs stopping the same, overoW-valve having disk 19, pin 20, screw-plug having indentation 21, steam-tube 15, secured on the inside of the steam-connection 14:, large threaded end 6, substantially as shown and described.

2. In an ejector and injector, as above de scribed, combining-tube 2, having handle 3, having arms 4, beveled lips 5, perforations 7 l8 9, mixer-tube 12, secured Within said combining-tube, stuffing-box 11, substantially as shown and described.

3. The combining-tube 2, the mixer-tube 12, and discharge-tube projecting through the shell 1, which are reciprocated at the will of the operator so as to draw or lift Water and to regulate the supply.

4. In an ejector and injector, as above described, the combining-tube 27 having mixertube 12, perforations 7 8, and 9, the closed end of said tube projecting through the shell 1, and adapted to being moved back and forth by means of the'handle 3, arms 4C, and beveled lips 5, working on the threaded neck 6, or equivalent means.

5. In an ejector and injector, as above described, the combination of the shell or body 1, having perforations 16 17 18, and screwplugs stopping the same, steam-tube 15, secured on the inside, steam-connection 14, large threaded neck 6, and stufiing-box 10, secured on the small threaded neck 11, with combining-tube 2, having perforations 7 8 9, mixertube 12,screwing inside of said tube, substantially as shown and described, andfor the purposes set forth.

In testimony whereof I affix my signature in presence of two Witnesses.
